Using the Suzaku space telescope, astronomers have conducted an X-ray spectral study of the nearby merging galaxy cluster Abell 3376 and its two arc-shaped radio relics. The new research reveals more insights into the properties of the radio sources in this cluster. The findings are presented in a paper published June 20 on arXiv.org.

Abell 3376 is a nearby bright and moderately massive merging galaxy cluster. It has two giant arc-shaped radio relics in its outskirts. Radio relics are diffuse, elongated radio sources of synchrotron origin, occurring usually in the form of spectacular single or double symmetric arcs at the peripheries of galaxy clusters.

Since structure in the universe forms in a bottom-up fashion, with smaller structures merging to form larger ones, modeling the merging process in detail is crucial to our understanding of cosmology.

At the current epoch, we observe clusters of galaxies undergoing mergers. It is seen that the two major components of galaxy clusters, the hot intracluster gas and the dark matter, behave very differently during the course of a merger.

Using the N-body and hydrodynamics capabilities in the FLASH code, we have simulated a suite of representative galaxy cluster mergers, including the dynamics of both the dark matter, which is collisionless, and the gas, which has the properties of a fluid. 3-D visualizations such as these demonstrate clearly the different behavior of these two components over time.
